However, in computer science, the motivation to build digital fashion archives is generally short-sighted and primarily to predict the next fashion trends that can be used by vendors to plan production or by online stores to improve recommendation engines. In contrast, in this study the aim is to describe the long-term fashion trend and explain why it occurred. Several studies have created their own fashion image databases to fit the fashion business issues they focused on [1]}, [2]}, [3]}, [4]}, [5]}, [6]}. Table REF  presents the best-known public databases from fashion studies in computer science. Fashionista is a representative fashion image database from the early stages of fashion analysis that uses computer vision techniques [1]}. The images in Fashionista were collected from Chictopia.com, a fashion blog. They contain pose annotations for fourteen body parts and clothing labels on superpixel regions. There are no location, timestamp, or fashion style annotations.
